1. What does the group need to accomplish by the end of the project?

FASTEST BALL CHALLENGE: The main objective of this challenge is to determine the angle of inclination, 0 , for which the time of travel across the horizontal track will be least. We will have to make use of the concepts of conservation of energy, kinetic and potential energy to win this challenge. Students will also make use of a stopwatch and photogate sensors in their data acquisition.

CAFFEINE EXTRACTION: In this experiment you will extract caffeine from tea. You will encounter the following techniques:
1) B├╝chner filtration
2) Solvent extraction
3) Distillation using a rotary evaporator

2. How will you know whether or not your project has been successful? 

FASTEST BALL CHALLENGE: Our ball will be the fastest among everyone else's balls! And our calculations will be precise and accurate, supporting our hypothesis.

CAFFEINE EXTRACTION: We are able to successfully extract the encouraged amount of caffeine using all three methods.
